With logic that is at best tortured, she states that, as marijuana smoke "causes cancer" (maybe; so does sunlight), and as legalization would cause use to increase 30 percent (how this figure was arrived at is not explained), substance abuse costs (to whom?) would increase 30 percent. I've spoken to people who were on drugs who made more sense than that. William Raffetto Moraga - --- MAP posted-by: Richard Lake
